Patient's question:
Here is the English translation of the provided text, with the return characters kept as they are:"I have been experiencing pain during urination again in the last two days, and my testicles are swollen. When I go to the toilet, there is also blood in my urine. At first, I thought it was my testicles, but after going to the hospital for a check-up, the doctor said it was prostatitis. Could you please explain the difference between orchitis and prostatitis?"
Doctor's answer:
Prostatitis is mainly caused by chronic inflammation. The main symptoms include frequent urination, urgency to urinate, and aching discomfort in the perineum. Most cases of prostatitis are non-bacterial, with only a small number being bacterial prostatitis. Orchitis and epididymitis are primarily caused by bacterial infections. In addition to pain in the testicles and scrotum, symptoms may include swelling of the scrotum. In more severe cases, fever may occur, and a blood test may show elevated white blood cell counts.
